WATER' CLOSET CISTE RN.

SPECIFICATION forming part of Letters Patent No. 274,214,. dated March 20, 1883. Application filed July 20, 1881. (No model.)

To all whom it may concern:

Beit known that I, CHAS. H. MOORE, a citizen of the United States, residing at Yonkers, in the county of Westchester and State of New York, have invented a new and useful Water- Oloset Uistern, of which the following is a specification.

My object is to furnish a flushing-cistern for water-closets from which a given amount of Water only can be drawn at each discharge of the closet, and to provide a retainerin the service-box to supply the closet with a desired quantity of water after the termination of the first flushing and closing of the water-closetdischarge valve. It is likewise my object to 'furnish a simple means of supplying the cistern.

In the accompanying drawings, making a part of this specification, Figure 1 represents a central vertical section. Fig. 2 represents a top view.

A shows the main tank, and A a measuring-compartment formed by a vertical partiport, B", in the vertical partition by preference.

G shows a service-box having a valve, 0, cp-

' crating on the discharge-port N. Said valve 0 is provided with a stand-pipe, M, which extends far enough up into the service-box to retain sufficient water in the service-box to furnish a closet with the desired quantity of'water when the outlet-valve is shut. Upon the lever H being depressed the valve 0 closes the port N, and the valve D opens and admits water to the service-box G, and from thence through the stand-pipe M to the closet. Upon the valve D being opened the mechanism is arranged to closethe valve E of the port B. This prevents any admission of water from the main cistern A, so that when the closet is held open the compartment A empties, while the water in the main cistern A is retained. Water is also retained in the service-box up to the mouth of the stand pipe M. Upon releasing the lever H the valve (3 is opened and the contents of the service-box deliveredto the closet, where it is again held until the next action of the closet.

The cistern can be made of wood and lined with suitable metal; but in this case it is shown made in one piece having a dividing- 1When this plate or partition J is used in a wooden cistern lined with metal it is placed in as shown and soldered to the metal lining.

Heretofore iron cistern service-boxes have been exposed to the action of water, the result of which is an accumulation of rust on the inner walls, and as water leaves the cistern sudden] y it becomes agitated in the service-box and dis colored with rust, and in this stateitis delivered to the delfbowl of the water'closet, which fin ally becomes discolored. To provide against this 1 line the service-box with a metal that will not rust. Thislining F is fastened to the plate J in a manner to prevent water coming in contact with theiron box. The port B on the vertical partition K is provided with a valve-seat and a bar extending across-it with a hole in the center for the spindle of valve E to operate in to guide saidvalve E to its seat. The valve E is also provided with a loop, into which the part 11 of the lever H enters to open and close the said valve E.

H represents an anglelever, the part H" extendingdown into the cistern, where it is intended to open and close the valve placed on the port 13 of the partition'K. The said lever would also operate a valve if placed on the opposite side of the partition from where the valve E is shown. I

I represents a support stationed in the cistern, to which the lever H is secured to operate the discharge-valves.

The'supply-valve of the cistern is made to close with the pressure. A screw-thread is made in neck L of chamber S, and a corresponding thread on spindle U, which, upon being turned in, forces the valve to into the chamber P, permitting water to flow into the cistern. Upon turning the spindle the opposite way the valve a is drawn tight against the valve-seat formedon the endot' chambers. that screws into the chamber P. This chamber P is provided with a screw-nut, e, which, when removed, leaves an opening large enough in said chamber P to pass the valvea through it to renew the washer. The chamber S can he I to avalve operating on a port in a vertical parcast in one piece with chamber P if desirable, but I prefer making it separate, to screw on after the chamber P is secured to the supplypipe. The packing-nut It is screwed on the neck L to prevent leakage. The outlet-port '1 of the'chamber S has a thread cut on it, into which a solder coupling is screwed. It is intended to solder a tube to said coupling to conduct water noiselessly to the bottom of cistern. The valve is operated by a weighty float, 0, secured on the end of lever f. To provide a cheap float of suflicient weight, I make it of enameled earthenware or wood, and have a hole made through to allow the leverf to pass through the center, where it is made firm by the use of a nut. B showsthe overflow of the cistern.

Havingdescribed myinvention,what I claim as new, and desire to secure by Letters Patent, 1s-- 1. In a water-closet cistern having a compartment formed by a vertical partition and supplied from the main cistern through a port in said partition, the-service-box G, having a Ineans'provided in it for retaining a reserve of water until after the termination of the first flushing and closing of the inlet-valve D of the service-box G and the outlet-valve of the closet, and then delivering it to the closet, substantially as described.

2. In a water-closet cistern having a compartment divided from the main cistern by a horizontal plate in the bottom of cistern, said compartmentbeing arranged to be empty at all times when the closet is not in use, the valve 0, having a tube, M, attached to it, substantially as shown, and a way through said tube M for the discharge of water to the closet when the valve 0 is closed, in combination with the discharge-pipe N, overfiowfipe B, and inlet-valve l).

3. The combination, with the service-box and inlet-valve D, of the horizontal plate J. having a margin of thicker proportion than the plate, and a calked lead joint, g, made between the margin and sides of the cistern, substantially as shown.

4. In a water-closet cistern, the lever H, having the part H cast or secured to it in a rigid manner and extending down into the cistern tition.

5. In a water-closet cistern having a vertical partition with a port in it near the bottom, a valve-seat fitted in the port of the partitlon, and having a guide acrossthe center, and a valve-spindle operating in said guide, substantially as shown.

6. The combination, with a water-supply valve, of a float with a vitreous surface, provided with a passage, 00, through its center, and a lever, f, extending through said passage, as and for the purpose set forth.

7. In a water-supply cook, the combination, with the inlet-chamber P, valve a, operating in inlet-chamber P, and closing in the direction with the pressure-valve seatp in chamber P, outlet-chamber S, neck L, having aspiral groove cut in the inner walls, and spindle U, having a spiral thread cut on it corresponding with and operating in grooves in the neck L, of the packing-nut It, fitted on the spindle U and screwed on the end of neck L, inclosing the grooves on the spindle and in the neck L, within said neck L, substantially as shown.

8. In a water-supply cock, the combination, with the inlet-chamber P, inlet-port U of the chamber P, valve a, operating in chamber P, and closing in the direction with the pressurevalve seat 1) in. chamber P, outlet-chamber,.

neck L, having a spiral groove in it, and spindle U, of the nut e, screwed in the end of chamber P, the lever f, and float O, substantially as shown.

9. In a water-cock, the combination, with the inlet-chamber P, valve a, operating in inlet-chamber P, and closing in the direction with the flow of water against the seat 19, and

outlet-chamber S, of the neck L, having a spiral thread cut in the inner wall, but not extending through said wall, and the spindle U, having a spiral thread cut in it to correspond with and operate'in the thread cut in the neck L, substantially as shown, and for the purpose of opening and closing the valve a, as set forth.
